FUNCTIONAL DESCRIPTION
CAUTION:
•Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.
Shaft lock
Fig.1
CAUTION:
•Never actuate the shaft lock when the spindle is moving. The tool may be damaged.
Press the shaft lock to prevent spindle rotation when installing or removing accessories.
Switch action
Fig.2
CAUTION:
•Before plugging in the tool, always check to see
that the switch trigger actuates properly and returns to the "OFF" position when released.
To start the tool, simply pull the switch trigger. Tool speed is increased by increasing pressure on the switch trigger. Release the switch trigger to stop.
For continuous operation, pull the switch trigger and then push in the lock button.
To stop the tool from the locked position, pull the switch trigger fully, then release it.
Speed adjusting dial
Fig.3
The rotating speed can be changed by turning the speed adjusting dial to a given number setting from 1 to 6 (6 at the time when the switch trigger is fully pulled).
Higher speed is obtained when the dial is turned in the direction of number 6. And lower speed is obtained when it is turned in the direction of number 1.
Refer to the table for the relationship between the number settings on the dial and the approximate rotating speed.
Number | |
1 | 1,500 |
2 | 1,700 |
3 | 2,000 |
4 | 2,500 |
5 | 3,300 |
6 | 4,000 |
006448
CAUTION:
•The speed adjusting dial can be turned only as far as 6 and back to 1. Do not force it past 6 or 1, or the speed adjusting function may no longer work.
•If the tool is operated continuously at low speeds, the motor will get overloaded and heated up.
Electronic function
The tools equipped with electronic function are easy to operate because of the following features.
Constant speed control
Possible to get fine finish, because the rotating speed is kept constant even under the loaded condition. Additionally, when the load on the tool exceeds admissible levels, power to the motor is reduced to protect the motor from overheating. When the load returns to admissible levels, the tool will operate as normal.
Soft start feature
Soft start because of suppressed starting shock.
ASSEMBLY
CAUTION:
•Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.
Installing side grip (handle)
CAUTION:
•Always be sure that the side grip is installed
securely before operation.
Remove one of the screws which secure gear housing and head cover, then screw the side grip on the tool.

OPERATION
Fig.8
WARNING:
•It should never be necessary to force the tool. The weight of the tool applies adequate pressure. Forcing and excessive pressure could cause dangerous disc breakage.
